The DBH 9459 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 58 mm shaft, 78 mm housing and 8 mm height, and Lx design, it is a replacement part for rotating equipment where sealing must be reliable and repeatable. MR Accesorios Industriales sells it as part of its seals and oil seals line.

The DBH 9459 is a single-lip radial shaft seal, identified by its designation 9459 and by the Lx design shown on its product page. Its nominal dimensions are 58 mm shaft diameter, 78 mm housing diameter and 8.00 mm height. That combination places it in the range of medium-size oil seals, intended for shafts that rotate inside a machined housing. The flexible lip runs on the shaft surface and, depending on the material and the mounting, can accommodate small misalignments or eccentricities typical of the equipment.

This type of seal is used in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where a shaft passes through a cover or a support. It also appears in machine tools, mixers and conveyors, whenever oil or grease must be separated from the outside environment. In food, paper or water treatment plants, the choice of lip compound and spring becomes more important due to contact with moisture or cleaning agents.

To select a seal such as the 9459, verify that the three dimensions match the shaft, the housing and the seat depth. Check the condition of the surface: a scratched or worn shaft means the lip will not seal even if the dimension is correct. During mounting, lubricate the lip with the same grease or oil used in the equipment, avoid hitting it and make sure it enters perpendicular to the housing. If the seal replaces another one, also compare the lip design and the spring type before installing it.

If you cannot find part number 9459 or need a nearby size, send us the data of the old seal: shaft diameter, housing diameter, height and a photo of the lip face. With that we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the equipment works at unusual temperature, speed or pressure, so that the choice does not fail a few hours after running.
